Michelin a Constant Ally in Porsche Penske GTP Triumph
Porsche Penske Motorsport won back-to-back GTP season titles at Motul Petit Le Mans in front of a sold-out crowd at Michelin Raceway Road Atlanta on Saturday. This marks Matt Campbell and Mathieu Jaminet’s second IMSA WeatherTech SportsCar Championship title together—their first came with Pfaff Motorsports in 2022.
“So to finally grab it with the six crew, with everyone involved after these three years, grab the manufacturer championship and grab it with Matt, it's really a dream come true and I'm just thankful,” said Jaminet.
No. 6 Porsche 963 had a strong performance in the 10-hour finale, finishing with a podium in third place. Jaminet gives credit to his Michelin tires for helping the team be in championship contention throughout the entire season.
“It was really pretty incredible when you look at it, we did tons of hours of racing in the night, in the dry, on slicks, in the wet in Watkins Glen, all kind of things, you know, we had to face this year,” Jaminet said. “On our end, obviously it worked out well. We don't really struggle with the tires; everything was really great this year, so we can't complain.”
The No. 31 Whelen Motorsports Cadillac won the 28th Annual Motul Petit Le Mans with Earl Bamber, Jack Aitken, and Frederik Vesti. This was the team’s second straight win this season launching Aitken to second place in the drivers championship.
